ArrayIndexOutOfBoundsException with 16 bit audio

Question

Hi, when converting 8 bit audio I have no exceptions, but when converting 16 bit I get an AIOOBE. Here is the code segment that deals with the conversion:
try {                          
  for (int r=0; r < audioShortData.length-1; r++) {
    loByte = audioByteData[r * numChan + 0];                
    hiByte = audioByteData[r * numChan + 1];
    //convert bytes to int
    sample = (hiByte << 8) | (loByte & 0x00FF);
    //samples array
    audioShortData[r] = (short)sample;
} catch (Exception ex){ex.printStackTrace();}The exception is pointing to: loByte = audioByteData[r * numChan + 0];
Thanks!

My proposal:
try {                          
  for (int r=0; r < audioShortData.length; r += 2) {
    loByte = audioByteData[r + 0];                
    hiByte = audioByteData[r + 1];
    //convert bytes to int
    sample = (hiByte << 8) | (loByte & 0x00FF);
    //samples array
    audioShortData[r/2] = (short)sample;
} catch (Exception ex){
  ex.printStackTrace();
}Just a quick guess, I'm pretty sure I can't think straight anymore right now.
